This dataset contains physical oceanography and fish abundance collected by CTD, surface trawl, and tagged fish from the research vessel Hokko Maru in the Central Bering Sea.

This dataset contains water temperature, salinity, zooplankton, and fish survey (salmonids and other pelagic fishes) data taken by CTD, nets, and trawls from research vessel Hokko Maru in the Bering Sea. This cruise is U.S. State Department MSR U2021-002 as part of the World Data Service for Oceanography. Data are in XLSX format.

Data from opportunistic tagging studies in the southest Bering Sea 2002-2003. Individually numbered loop spaghetti tags released during research cruises; all recoveries from fishing industry. Main release groups in February 2003 at two locations: 1) N of Cape Sarichef, Unimak Island, and 2) off Amak Island, north of the Alaska peninsula. Other smaller releases at several locations in southeat Bering Sea from April 2002 to November 2003. Pacific cod (Gadus macrocephalus) caught with commercial and research pot gear from depths of 50-150 meters; length of tagged fish primarily 50-80 cm. Data in MS Access format (digital tabular). Data include lat/long of capture and release locations, release date/time, fish length and condition at release. Recovery data includes location and date of recovery, recovering vessel and gear, fishery observer, recipient for tag reward. Most recovery locations in lat/lon to nearest minute, some to state or federal stat area only; variables code quality of recovery location and date info. Most records include length, weight, sex, and condition of recovered fish, some otoliths collected. Recoveries primarily documented by fishery observers on vessel or at delivery plant. Database includes tags recovered through Dec 2007. Total of 6871 tags released, 2634 tags recovered. Important caveats: 1) tags released opportunistically, not in design or associated with quantitative model, 2) most tage releases were in main commercial fishing ground during fishing season, assumptions of mixing with overall population are invalid, 3) all recoveries through industry, spatial and temporal distribution of recovery effort very non-uniform, some areas little or no effort. Raw data including coordinates of tag recoveries and vessel information are considered observer data and are confidential under the Magnuson-Stevens Act.

This dataset contains fish/shellfish survey data collected in the Bering Sea from June 14, 1985, to August 8, 1986, by Douglas Martin, Envirosphere Co. Data has been processed to the NODC standard Fish/Shellfish Surveys (F123) format. The F123 format is used for data from field sampling of marine fish and shellfish. The data derive from analysis of midwater or bottom tow catches and provide information on population density and distribution. Cruise information, position, date, time, gear type, fishing distance and duration, and number of hauls are reported for each survey. Environmental data may include meteorological conditions, surface and bottom temperature and salinity, and current direction and speed. Bottom trawl or other gear dimensions and characteristics are also reported. Catch statistics (e.g., weight, volume, number of fish per unit volume) may be reported for both total haul and for individual species. Biological characteristics of selected specimens, predator/ prey information (from stomach contents analysis), and growth data may also be included. A text record is available for comment.

Spawning season data of Mid-Atlantic finfish, collected by various ships (Delaware II, Albatross II, Atl. Twin, Xiphias, and the Rorqual) as part of study "The Biology of Marine Finfish" done by Sandy Hook Laboratory of National Marine Fisheries Service, Highlands, NJ. Data parameters include: Vessel, cruise number, Latitude, Longitude, date, time, distance fished, depth, wind and current measurements, gear descriptions (mesh size, number of floats, length of trawl, etc), taxonomy, sex, age, stomach and gut contents, egg color, number, and condition. Data were originally recorded on a 9-track tape in EBCDIC (1600 BPI) and have been converted into current NODC data storage format. The documentation includes a detailed description of the record format.
